Run a franchise

Manager Mode

Pick any franchise across a bundled or custom world. Build a roster, negotiate contracts, and navigate the cap.

Run scrims to sharpen chemistry. Send scouts after prospects. Pull off the franchise-altering trade at the deadline.

— FAQ

Stuff people
actually ask.

Couldn't find an answer? Join the Discord, we usually reply within a few hours.

Open Discord

No. The whole game is free: every mode, every era, MyPlayer, Expansion teams, advanced analytics, cloud saves, and the desktop app. Sandbox Pro is an optional plan from $2.92 a month that adds cloud save slots and removes ads, and it never unlocks gameplay.
